I To all whom it may concern:

Be it known that I, LEwIs W. DELP, a citicounty of Peoria, and State of Illinois, have invented a new and useful Hoisting-Machine,-

of whichthe following is a specification.

- This invention pertains to improvements in hoisting-machines, but more particularly to a machine for returning the hay carrier or fork to the loading or starting position after ithas deposited its load of hay within the ;barn.

August 11, 1903.

Furthermore, the object of the invention is to provide a new combination of elements in member of the frame shown in Fig. 6, showing part of the frame in section. Fig. .4 is a view of an adjustable fork for one of the wheels or pulleys of my im roved machine.

Fig. 5 is a side view of the w eel carrying the fork shown in Fig. 4. Fig. 6 is a perspective view of the entire frame showninFigs. 1 and 3.

The frame of the machine consists ofa U- shaped member a, inverted, as shown in Fig. 1.

two slots 8 for convenience in attaching the frame to the barn or other building to be filled with hay. This, however, will be more fully describedv hereinafter.- Within the frame just described is a central depending member, also indicated by 0, being part of the entire frame, said member being formed with the balance of the frame or secured thereto in suitable manner. Thus construct- 5 ed the frame now comprises three parallel members about evenly spaced apart, and

v two of the members are provided with short arms 0 at right angles forpurposes to be described later. At the extremities of all three members is carried a-horizontalshaft x, on. which is secured near one end between two.

ing attac is not shown, however. In the top or curved portion of sa1d frame are of the adjacentmembers a wheel E, consisting of the rim T and the spoke-arms G, together with the hub P, by which the wheel is held firmly on the shaft ac by means of a setscrew K. Near the opposite end of the shaftw is a pulley-wheel D, between the central and 3 outer arms of the frame and also held securely on the shaft by means of the set-screw J. The spoke-arms G of the wheel E are extended beyond the rim T, as shown, where they present abroad surface at right angles to the plane of rotation of the wheel. Each arm thus extended is provided with a slot H in line with the s okesthemselves, as shown in Fig. 1. A for F- is next provided, having a flat portion adapted to be clamped to each extension by means of a bolt 1, the slots I-I allowing of adjustment of'the forks toward and away from the shaft w.

L is an iron rod supported at the free .ends of the arms 0 o, hereinbefore described, and from said rod is suspended a pulley w, over which runs a rope m. From said rope a series of weights V are suspended by means of two strands of chain at, there being, however, but two of the wei hts shown in the drawings, as this feature Ilas been described in my former patent referred to and needs no further description here.- About the pulley D and secured at its end to it is a rope B, the opposite end passing down through all the weights to. the bottom one, to which it is secured; but this has been described also in my former'p'atent and I will not enlarge upon it here. The wheel E is likewise rovided with a rope 0, one end'being fastened to the wheel, (fastenin not shown,) the opposite end havcut with the hay-carrier, which In operation, the parts being positioned as shown, the rope 0 being wound upon the wheel E,' the hay-fork-having its load to be deposited is drawn along the track (usually provided, but not show and the load is deposited where wanted; In pulling the load to its place the wheel E is turned by the unwinding of the rope C therefrom, and this action winds up the rope B upon the pulley D,

thus raising the-wei hts V from below.- Thisat once places aloa upon the said pulley D, the tendency of which is to fall and reverse the directionofrotation of said pulley and the wheelgE. The load being deposited and the rop 0 being released at the carrier end,

the weightsimmediately begin their descent, thereby-unwinding the rope B and winding the rope 0 upon said wheel E, thereby returning the carrier to its starting position to again receive its load to repeat the operation just described. By extendin or retracting the forks F of the wheel E the diameter of the latter may be changed. The purpose of this adjustment may be understood from the following: Barns are not always constructed of a uniform size, their relative lengths and heights being variable. Consequently the distance the hay-carrier must move on its track in some cases as compared with the distance the hoisting device is from the ground is either too much or too little to give the Wei hts the proper distance in which to travel, so t at if the wheel E were fixed in size the weights would either not reach the ground or would be so near the ground as to lie thereon at times, thus losing the advantage sought to be derived from the use of said Weights. Now by having the wheel adjustable it maybe changed to suit circumstances. When the barn is long for its height, the wheel is increased in size, thereby giving a greater circumference by which the rope can be taken up without affecting the distance of travel of the weights. When the barn is short for its height, the wheel E is made smaller in diameter, so that the same number of revolutions are imparted to the drum D as before, so that the movement of the weights will be the same as in the first instance. By means of the rope m all of the weights may be raised to a position where their action in descending will return the carrier only part Way, so that hay may be readily moved from one end of the barn to the other or from one place to another when it is desired to rearrange hay-stacks and the like. Said adjustment of the weights is to permit the carrier to have greater or less distance of travel as may be found necessary in certain cases, as will be understood.

The slots 8 in the top of the frame 0 c are for the purpose of permitting any desired adjustment of that member upon the barn or other building, so that .it may be placed at any angle found necessary, a bolt passing through each slot into the building being suflicient to retain the said frame in any position.

I am aware of the state of the art in hoisting apparatus, and therefore claim 1. A hoisting-machine comprising a supporting-frame substantially in the form of an inverted U for attachment at its top to the barn, a shaft having bearings in said frame, a wheel afliXed to said shaft and constituting a winding-drum, a cable for such wheel, the

' said wheel being capable of adjustment to increase or decrease its diameter for the purposes set forth, a second smaller wheel on the said shaft also constituting a winding-drum, a cable attached to said latter wheel a series of weights, suspended beneath said wheel to the lowest of which the said cable is attached, and means for supporting all of the weights and adjustin them vertically all for the purposes set fort 2. A hoisting-machine comprising a supporting-frame substantially in the form of an inverted U for attachment at its top to the barn and adjustable at any angle, a shaft having bearings in said frame, a wheel affixed to said shaft to constitute a windingdrum, a cable attached to said wheel and also to the hay-carrier for the purposes described, the said wheel capable of adjustment for increasing or decreasing the diameter thereof for the purposes set forth, a second smaller wheel on said shaft also constituting a winding-drum, a cable afiixed thereto, a series of weights suspended beneath said latter wheel and having the said cable attached to the lowest one, both cables being oppositely wound upon their respective wheels, one of them unwinding as the other is wound up all for the purposes indicated.
